An injection mold component for molding the outer surface of a preform neck, which allows improved cooling of the preform neck inside the mold, while at the same time reducing the mold cycle time. A related production process of said injection mold component, which allows the section of the cooling channels to be optimized, determining a more effective cooling, is also described.

An air activating and air cooling mold device utilized to process a workpiece includes a mold and an intake device. The mold has at least one gas channel disposed therein, and each of the at least one gas channel has an inlet and at least one outlet. The inlet is disposed on an outer surface of the mold. The at least one outlet is disposed on the outer surface of the mold, is spaced apart from the inlet, and communicates with the inlet. The workpiece is disposed on the mold and covers the at least one outlet. The intake device is mounted to the inlet of the at least one gas channel of the mold, such that gas is injected into the mold via the inlet and flows out of the mold via the at least one outlet.

An optical lens injection molding module is presented, wherein the molding module has a mold core made by a metal 3D printer. The metal 3D printer first lays metal powder on a platform and then transmits laser heat energy for irradiation sintering to melt the metal powder together into a predetermined shape as a metal layer, and by repeated formation of a plurality of metal layers. The mold core has a top surface, a bottom surface, a peripheral wall, a through aperture, a plurality of mold cavities, and at least one temperature controlled flow channel. The mold cavities and the temperature controlled flow channel are disposed in the mold core. The through aperture is disposed at a center of a circular position of all the mold cavities, penetrates both of the top surface and the bottom surface, and connects radially to each mold cavity via a plurality of guiding grooves.
